j1yant,

From the man page for echo, I found the following...

DESCRIPTION
The echo utility writes its arguments, separated by BLANKs
and terminated by a NEWLINE, to the standard output. If
there are no arguments, only the NEWLINE character will be
written.

So this explains why you always get a newline.

Also, in that man page, you'll see that some echos ( shell dependant ) allow for a flag to be passed to eliminate the adding of a NEWLINE to the end of the character.

Hope this helps...
T

puts(3C)						   Standard C Library Functions 						  puts(3C)

NAME
puts, fputs - put a string on a stream SYNOPSIS
#include <stdio.h> int puts(const char *s); int fputs(const char *s, FILE *stream); DESCRIPTION
The puts() function writes the string pointed to by s, followed by a NEWLINE character, to the standard output stream stdout (see Intro(3)). The terminating null byte is not written. The fputs() function writes the null-terminated string pointed to by s to the named output stream. The terminating null byte is not writ- ten. The st_ctime and st_mtime fields of the file will be marked for update between the successful execution of fputs() and the next successful completion of a call to fflush(3C) or fclose(3C) on the same stream or a call to exit(2) or abort(3C). RETURN VALUES
On successful completion, both functions return the number of bytes written; otherwise they return EOF and set errno to indicate the error. ERRORS
Refer to fputc(3C). USAGE
Unlike puts(), the fputs() function does not write a NEWLINE character at the end of the string. ATTRIBUTES
